then retry the DAT command.
3. You should see a $
nmdat>
prompt.
4. Enter a GETDUMP command in the format "GETDUMP xxxxx" where the xxxxx is the
5-character dump name you gave to the dump.
5. The console displays an I/0 Request message for the dump tape. Reply as normal.
6. Monitor the subsequent process for unusual error messages.
a. The DAT utility may abort because of insufficient disk space. The memory dump may
require hundreds of thousands of sectors of permanent disk space on the system. If there
is not enough space to accomplish this task, the DAT utility aborts. Report this event
to the Response Center.
7. Once the dump is finished, type EXIT to leave the utility.
The memory dump now resides as file(s) in the DAT.TELESUP account.
Step 6: Call the Response Center.
In the last step, you gather information and call the Response Center to report the system
interruption:
1. Gather the following information to give to the Response Center engineer who will be
calling back:
a. The modem telephone number and Baud rate.
b. The passwords to MGR.TELESUP and any additional security provisions needed to
access the system on which the memory dump resides.
c. The operating system release (type :SHOWME to get current release number).
d. All troubleshooting information gathered so far.
2. Call the Response Center. If you are certain the problem is hardware, ask for "Hardware
Assistance." Report the full system abort message printed on the console and the contents
of the hex display. Also report any unusual messages encountered during the subsequent
system startup.
3. The Response Center recommends that you allow users to log back on, without waiting for
the Response Center engineer to call back.
If you choose to wait for the Response Center engineer to call back before allowing users
back on, please note this fact to the Response Center Coordinator so that your call is
appropriately prioritized.

this core file can be analyzed using special tools to determine more about what caused the
panic.
Saving a core file is a two-part process:
